I'd like to suggest an option to make damage boosts, such as the ones from wolver lines, mad bomber, and UVs, have some sort of effect that can be noticed by others.
It could be nice for when you've got some super powerful weapon of death, and some other knight is playing keep away with the monster you're trying to hit, thinking that their big, high knockback sword must automatically have the best damage. On top of that, it might be pretty, which is definately important.
Possible implimentations:
-A mild aura of some kind, maybe a faint red sunshine aura.
-Weapons' swings/explosions/other flashes could become brighter, or more saturated, or even tinted with personal color.
-Weapons' attack noises could become higher pitched.
-To be dramatic, afterimages similar to Avengers and Fausts could be added to other weapons with boosted damage, and extended to the point of hilarity on Avengers and Fausts with boosted damage.
-A simple "+6" or "-2" or "0" displayed somewhere. Near names, maybe, or portraits.
Again, I'd prefer this as an optional thing. Maybe two options, one for if you want your damage boost to be displayed, and one for if you want to be able to see damage boosts that people have allowed to be displayed.
You could always just look at your teammate and say "Yep, he's a furry guy, he has a damage boost."
People hitting enemies out of the way is not that big of a problem. In fact, it only shows your own hastiness.
Actually, if they won't even pay attention to the clothes you're wearing, what makes you think they'll pay attention to this? Or better yet, even know what any of it means.
Like the idea, though.
